摘要： To perform erasure detection for an intermittently active transport channel with unknown format, a receiver determines an energy metric and a symbol error rate (SER) for a received block with CRC failure. The receiver computes uncorrelated random variables u and v for the received block based on the energy metric and SER, the estimated means and standard deviations of the energy metric and SER, and a correlation coefficient indicative of the correlation between the energy metric and SER. The receiver then evaluates the uncorrelated random variables u and v based on at least one decision criterion and declares the received block to be an erased block or a DTX block based on the result of the evaluation. The decision criterion may be defined based on a target probability of false alarm and adjusted based on another metric, such as a zero state bit, for the received block.

摘要： Erasure detection and power control are performed for an intermittently active transport channel with unknown format. A receiver processes each received block and determines whether it passes or fails CRC. For each received block with CRC failure, the receiver performs erasure detection by computing a symbol error rate (SER) and energy of the received block, comparing the computed SER against an SER threshold, comparing the computed energy against an energy threshold, and declaring an erasure if the computed SER is less than the SER threshold and the computed energy exceeds the energy threshold. The SER and energy thresholds may be adjusted based on the average SER and the average energy for prior received blocks with CRC failures. For power control, an SIR target is increased by an UP step whenever an erased block is detected for the transport channel.

摘要： Techniques for reducing interference with a multiple format channel in a communication system are disclosed. In one aspect, a minimum power level is determined for each format transmitted during a transmission interval. The minimum power level for formats that will experience the interference are increased to compensate. The power level selected for transmission during the transmission interval is the most stringent of the minimum power levels. Various other aspects are also presented. These aspects have the benefit of mitigating the effects of a known interfering signal, while avoiding unnecessarily increasing transmit power, thus reducing the interference to other users and increasing system capacity.

摘要： Apparatus and methods for power control for mitigation or control of interference in a wireless communications environment. Power control techniques can consider the effectiveness of interference cancellation before making power control determinations. For example, where interference with a base station from an interfering wireless terminal is being canceled such that the effects of that interference are not adversely affecting operations of the base station, the offending terminal can be left unchanged, or its transmit power can be increased. On the other hand, where the interference cancellation operation is not able to cancel the effects of the interfering signal sufficiently, the operation can lower the uplink transmit power of the offending signal so as to not cause interference to the other base station.
